Ive been looking to replace my lower triple clamp and shaft due to stripping the top of the shaft and top nut. Ive found that even before the considering the fork diameter, there are different lower triples. They appear to come in different shaft lengths. I have an 01 YZ426 and my steer shaft is 10-7/8" long. So far, Ive bought a 99 and an 02 of ebay that were like 10-9/16". The shaft isn't long enough to catch the threads on the lock nut. When I looked and compared part numbers, This is what I found: 99 YZ400 - 5DJ-23340-L0-00 99 WR400 - 5BF-23340-L0-00 00 YZ426 - 5HC-23340-L0-00 00 WR400 - 5GS-23340-50-00 *01 YZ426 - 5HC-23340-M0-00 01 WR426 - 5MV-23346-L0-00 02 YZ426 - 5NX-23340-L0-00 02 WR426 - 5NX-23340-L0-00 These numbers don't necessarily help my quest. When searching ebay, most of the people make a blanket statement like "should fit 99-02 YZs and WRs". I know this is not the case. When I searched TT, I found lots on triples, just nothing on this. Has anyone ran into this? Does anyone have a extra 01 lower laying around the garage?
